Here is how you think of it: The solenoid is a switch, in terms of the wiring. One big cable in, from the battery needs to connect to one big going out. These two terminals are larger and have a different size fastener and washer, than "the smaller one(s).

So a solenoid is an electromagnetic switch that in normally open (not allowing current between the contacts).
WHEN you put a voltage to the smaller terminal, the magnet energizes, and contact is made between the two big terminals, stop the voltage to this small terminal and the switch opens.

So, some soleniods have two smaller terminals. The puropse of the 2nd smaller terminal is to allow more voltage to be directed to the coil, only during starter engaugement. The reason for this is voltage to the coil has to be reduced, during normal operation, but this would not be enough during starting.

So, like an analog clock face, most are oriented as follows. 12 o'clock position is battery cable heavy in, 6 o'clock position is heavy out to the starter, 2 o'clock position is switch energize, and 10 o'clock position is coil feed out (light).

I figure the battery cable and starter out wires are self evident, by size. IF you were to reverse the light two wires, nothing happens, and no damage, reverse to the correct position and off you go.

I have a 93 ford f150. I'm switching the starter from one with a selenoid to no selenoid. Having major problems. Can you help

Use a Ford remote starter solenoid, here is a Standard brand part number and where to order it cheap.

Below is a simple wiring diagram of a remote starter solenoid, since you say the new starter will not have a solenoid hook directly to the starter B+ battery post. Mount the remote solenoid as close as possible to the starter, use bulk battery cable or see if they sell it in made up sizes of different lengths. Use the right color cable which is red (B+)

This is the part you need..
Below is a picture o the Ford solenoid you need.

I have a wiring overheating problem. The motor is a 1999 Mercury 125hp. The wiring by the starter selenoid keep melting, twice in 4 years. They're not touching the selenoid. I have replaced the ends both...

Make sure all connections are tight the wire is of the right guage and battery is of full charge. If the starter is dragging(turning slow) it will cause accessive heat to the wires and potential damage to the starter.

Please take a moment to rate my answee............... Thanks

Cannot fire the starter. Think it is an electrical issue. Is there a fuse that I need to check?


My name is Tom and I trust I can be of service to you.

I will now asume by "firing the starter" you mean the car will not turn over. I will also assume that you have checked the battery and it is able to make contact with the starter selenoid. The starter selenod is the salami shaped unit which is on top of the starter.

You will find that there are three contacts on the back of the selenoid. One is the ground to the engine block and the other are leads for the battery.

I will also assume that you do not want to take the starter off.(taking it off is the simplist way to check if the starter is bad or the starter seloid).

Back to checking the starter. Under the car looking up to the sunlight from the starter point of view, you will see a cable that runs from the starter selenoid to the battery. Also make sure that the ground wire(the wire which attaches to the engine block) is clean.

You now know that you have battery power to engauge the selenoid and the starter if both are working properly.

Attempt to start the car. If it does, you have solved the problem. If not,using a pair of jumper cables, attach one to ground and the red one to "short" the curcuit.

This is done by placing the red jumper cable clamp accross both non-grounded leads off the startrer selenoid. If you hear a click, then the starter seleniod is working. If you hear a click and the car turns over your starter and seleniod are both good.
If you do not get a ckick or a start then the starter and attached selenoid are both bad and need replacing.

I trust this will be of help to you please call or write and I will be happy to give you further assistance.

Intermittent starting problem. Turning key does nothing.

Sounds like you could have a faulty switch, but I would check the starter selenoid first. Sometimes when the selenoid goes bad it will behave in the way you describe. If, with your key in the on position, (not on start), you can jump power from the hot wire, (positive), post on your selenoid to the hot wire that goes from the selenoid to the starter and the starter then engages, but doesn't otherwise, it is a selenoid problem. Good Luck! I hope you find this very helpful!

The positive battery terminal cable goes to the input side of the solenoid along with another smaller wire that powers the rest of the car. The smallest terminal has one even-smaller wire that operates the solenoid from the ignition switch 'start' position. The output side has another cable which goes to the starter power terminal.

Won't start

its either a bad or drained battery or the starter selenoid. check your battery voltage using a tester or put it on a charger, if that doesnt solve your problem you should look at your starter selenoid
